CHARLES A. CASE, 0F SHELTER ISLAND, NEW YORK.

BROOM-BRIDLE.

To all whom t may concern Be it known that I. CHARLES A. CAsn, a citizen of the United States, residing at Shelter Island, in the county of Suffolk and State of New York, have invented a new and useful Improvementin Broom-Bridles, of which the following is a speciiication.

rI his invention relates to an improvement in stable, yard, or street brooms, the object of the invention being to prolong the life of the broom by removing from the broom bristles the strain which is usually thrown upon them at the point after they emerge from the broom back.

The invention consists of the novel features of construction hereinafter described, pointed out in the claim and shown in the accompanying drawings, in which,

Figure l is a longitudinal section through the broom back. Fig. 2 is a bottom plan view of the brush. Fig. 3 is a section on the line 3-3 of Fig. l. Fig. 4 is a section on the line 4-4 of Fig. 1.

In the construction of brooms the brushes are secured in suitable sockets formed in the underface of the back and the bundles of fibers forming the brushes emerge from the sockets in a compact mass being usually tightly secured at this point. The result is that as the broom is used the fibers bend at this particular point, but have no yielding movement in the sockets. The result is that they soon become broken by reason of the strain thrown upon them at this point. In my construction I overcome this objection by placing the bending point at a distance from the back and at a point where the various brushes or bundles of fibers composing the broom have been permitted to spread out, thereby permitting the said fibers to yield to the binding strain, thereby preventing breakage.

In the drawings, l represents a broom head provided with the usual handle 2.

Specification of Letters Patent.

Application led April 19, 1913.

Serial No. 762,379.

This head is provided with depending end portions 3, and carries the brushes 4, inserted and held in the broom head in any desired manner. Suitable staples 5 pass through the end portions of the broom, the free ends of the staples are bent over upon the upper portion of the broom head and are covered by a suitable metal casing 6 which ts over the head of the broom. Secured to the depending end portions 3 and held in place by the staples 5 are longitudinally extending wire strands 7, said wire being arranged in pairs and the wires of each pair are arranged zig-zag intersecting each other and inclosing between them the various bundles of fibers which constitute the brush. Preferably the pairs are so proportioned that the various bundles of fibers are held between these wires about one-third of the way from the brush head to the outer ends of said bundle. rIhis method of wiring the fibers removes the strain from point of engagement with the back and gives the bers a resilience which they would not otherwise have, and by reason of this fact the fibers may be slightly shorter than in brooms of the ordinary construction and at the same time have the same degree of elasticity without danger of their breaking off while in use.

Nhat I claim is A device of the kind described comprising a broom back, end extensions at right angles to the head, staples passing through the ends of the broom back, a casing covering the free ends of the staples, a brush carried by the back, said brush comprising a plurality of bundles, and wires secured under said staples and engaging said bundles at a distance from the broom back.
